Technical Field

[0001] The invention belongs to the technical field of crop sampling, and in particular is a crop sampling device for agricultural pest and disease analysis. Background Art

[0002] Rice is one of the main food crops in my country. During its growth, the occurrence of pests and diseases seriously affects the yield and quality of rice. At present, the way to detect rice pests and diseases is to detect rice leaves to see if they are infected with pests and diseases. In the process of sampling rice leaves, staff often need to go deep into the rice fields and directly contact the rice plants for sampling. However, the edges of rice leaves are sharp, and people can easily scratch their hands when sampling. This not only brings pain and injury to the samplers, but more seriously, hand injuries may lead to infection, affecting work efficiency and health. In addition, due to the fear of being scratched by rice leaves, operators may have scruples when sampling, and cannot guarantee the integrity of the rice leaves. Therefore, in order to solve the above problems, a crop sampling device for agricultural pest and disease analysis is proposed. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 12 As shown, the present invention provides a crop sampling device for agricultural pest analysis, comprising a housing 1, and further comprising: a winding assembly 2, which is mounted on the housing 1; a driving assembly 3, which is fixed to the side of the housing 1 away from the winding assembly 2 and is used to drive the winding assembly 2 to rotate an integer number of circles; a shearing assembly 5, which is arranged on the housing 1 and is used to shear the stem of rice leaves; an adjusting assembly 4, which is mounted inside the housing 1;

[0039] The winding assembly 2 comprises a connecting ring 21 movably connected to the inside of the housing 1, and two damping rollers 22 are symmetrically and movably connected to the connecting ring 21;

[0040] The shearing assembly 5 comprises an elastic plate 51 elastically hinged to the bottom of the housing 1, a shearing knife 52 is fixedly connected to one end of the elastic plate 51 away from the driving assembly 3, and a slope 511 is arranged at the other end of the elastic plate 51;

[0041] The adjustment assembly 4 includes two fixed plates 41 symmetrically fixed to the middle of the housing 1, and a notch 2 412 is provided on the fixed plates 41. A slider 1 42 is movably connected to the opposite side of the two fixed plates 41, and a slider 2 43 is movably connected inside the slider 1 42. A protruding rod 431 is fixedly connected to the slider 2 43, and both ends of the protruding rod 431 extend into the two groups of notches 2 412 respectively. A spring telescopic rod 44 is fixedly connected between the side of the slider 1 42 and the fixed plates 41. One end of the two sliders 1 42 extends to the outside of the housing 1 and is fixedly connected to a slider 3 45. A push rod 421 for pressing the inclined surface 511 is fixedly connected to the side of the slider 1 42 facing the inclined surface 511;

[0042] By adopting the above scheme, the end of the rice leaf away from the stem is extended into the shell 1 from the opening of the shell 1, so that the rice leaf is extended between the two damping rollers 22, and then the slider 3 45 is moved to drive the slider 1 42 and the push rod 421 to move toward the inclined surface 511, and the push rod 421 is pressed against the inclined surface 511, so that the elastic plate 51 rotates to drive the shearing knife 52 to move upward and shear the stem of the rice leaf, and then the driving component 3 is operated to drive the connecting ring 21 and the damping roller 22 to rotate to wind the rice leaf, thereby avoiding the situation that the operator may scratch his hands when collecting the rice leaves;

[0043] At the same time, since the driving assembly 3 drives the winding assembly 2 to rotate an integer number of circles each time, it is ensured that the two damping rollers 22 can still maintain vertical symmetry after the driving assembly 3 stops working, so as to facilitate the insertion of rice leaves.

[0044] like Figure 1-3 and Figure 5 As shown, the housing 1 and the elastic plate 51 are fixedly connected to the opposite sides with baffle plates 12, and the gap between the two baffle plates 12 is larger than the gap between the two damping rollers 22;

[0045] By adopting the above solution, two sets of baffles 12 are provided to ensure that the rice leaves can accurately enter the gap between the two damping rollers 22, thereby ensuring that the subsequent rice leaves can be stably rolled up.

[0046] like Figure 6 and Figure 8-9 As shown, the outer parts of the two damping rollers 22 are both provided with anti-slip strips 221 in an annular array;

[0047] By adopting the above scheme, since the damping roller 22 is movably connected to the connecting ring 21, when the connecting ring 21 drives the damping roller 22 to rotate to roll up the rice leaves, the anti-slip strip 221 can increase the friction when in contact with the rice leaves, and since the damping roller 22 has a damping effect when rotating on the connecting ring 21, the situation in which the rice leaves slip due to the damping roller 22 rotating too fast is avoided, and the stability of the damping roller 22 when rolling up the rice leaves is further increased.

[0048] like Figure 1-3 , Figure 5-6 and Fig. 9 As shown, a baffle plate 3 211 is fixedly connected to the connecting ring 21, and a baffle plate 11 is fixedly connected to the housing 1;

[0049] The bottom end of the connecting ring 21 is located below the gap between the two damping rollers 22, and the top end of the baffle 11 is connected to the outside.

[0050] By adopting the above scheme, after the rice leaves pass through the gap between the two damping rollers 22, the ends of the rice leaves can be guided by the baffle three 211 and the baffle one 11 to extend out of the outer shell 1, thereby preventing the rice leaves from accumulating inside the outer shell 1 and causing the rice leaves to be unable to completely enter the outer shell 1.

[0051] like Figure 2-3 and Figure 5-11 As shown, a discharge assembly 6 is arranged inside the housing 1; the discharge assembly 6 comprises a lever 61 hinged inside the housing 1 and located between the winding assembly 2 and the adjusting assembly 4, a slot 3 611 is provided on the lever 61, and in the initial state, the middle part of the convex rod 431 is sleeved on the end of the slot 3 611 away from the spring telescopic rod 44; the slot 3 611 is located between the two sets of slots 2 412, and the lengths of the two are equal;

[0052] With the above solution, when the slider three 45 moves toward the driving assembly 3, the limiting effect of the notch three 611 and the notch two 412 on the protruding rod 431 prevents the push rod 421 from accidentally pushing the rice leaves to move due to the ring 64 when squeezing the elastic plate 51 to shear the stems of the rice leaves.

[0053] like Figure 2 , Figure 5 , Figure 7 and Figure 9-10 As shown, the discharge assembly 6 also includes an elastic rod 62 elastically connected to the end of the lever 61 close to the winding assembly 2, a disc 63 is sleeved on the outside of the anti-slip strip 221, a ring 64 is movably clamped on the outside of the disc 63, and the end of the elastic rod 62 away from the lever 61 is hinged to the ring 64;

[0054] The fixing plate 41 is provided with a slot 1 411 which is equal to the slot 2 412 in width and connected to each other, and the lever 61 is provided with a slot 4 612 which is equal to the slot 3 611 in width and connected to each other;

[0055] The housing 1 is provided with a circular opening 13 located directly in front of the winding assembly 2;

[0056] The protruding rod 431 can move along the notch 1 411 and the notch 4 612 at the same time, and make the lever 61 rotate and drive the elastic rod 62 to move toward the circular opening 13;

[0057] By adopting the above scheme, the shell 1 is inserted into the preservation bag and the bag opening is submerged over the baffle 2 12, and the slider 3 45 is pushed to drive the slider 1 42 and the slider 2 43 to move toward the baffle 2 12. At this time, the protruding rod 431 will slide along the slot 4 612 and the slot 1 411 at the same time, thereby forcing the lever 61 to drive the elastic rod 62 to rotate, and then the elastic rod 62 drives the ring 64 through the disk 63 to push the rice leaves wound on the damping roller 22 out of the baffle 2 12, thereby facilitating the operator to preserve the sample.

[0058] like Figure 7 and Figure 9-11 As shown, the angle between the extending direction of the slot 2 412 toward the slot 1 411 and the slot 1 411 is α, the angle between the extending direction of the slot 3 611 toward the slot 4 612 and the slot 4 612 is β, and α is greater than or equal to twice β;

[0059] The ends of the slot 1 411 and the slot 4 612 away from the push rod 421 are mirror-symmetrical about the line connecting the axis of the push rod 421 and the lever 61;

[0060] By adopting the above scheme, through the design of notch one 411 and notch four 612, it is ensured that when the protruding rod 431 moves along the two, the lever 61 can drive the ring 64 and the disk 63 through the elastic rod 62 to completely push out the rice leaves wound on the damping roller 22.

[0061] The working principle and use process of the present invention:

[0062] First, the operator moves the end of the rice leaf away from the stem into the housing 1 through the opening of the housing 1. At this time, the rice leaf will be guided by the baffle 2 12 and extend between the two damping rollers 22. At the same time, the rice leaf will be guided by the baffle 3 211 and the baffle 1 11 and extend to the outside of the baffle 1 11. Then, the slider 3 45 is moved to drive the slider 1 42 and the push rod 421 to move toward the inclined surface 511, and the push rod 421 is pressed against the inclined surface 511, so that the elastic plate 51 rotates to drive the shearing knife 52 to move upward and shear the stem of the rice leaf. Then, the driving assembly 3 is operated to drive the connecting ring 21 and the damping roller 22 to rotate to wind the rice leaf.

[0063] When the rice leaf samples need to be preserved and bagged, the shell 1 is inserted into the preservation bag and the bag opening is made to cover the baffle 2 12. Then the slider 3 45 is pushed to drive the slider 1 42 and the slider 2 43 to move toward the baffle 2 12. At this time, the protruding rod 431 will slide along the slot 4 612 and the slot 1 411 at the same time, thereby forcing the lever 61 to drive the elastic rod 62 to rotate, and then the elastic rod 62 drives the ring 64 through the disk 63 to push the rice leaves wound on the damping roller 22 out of the baffle 2 12.
